Those funny little things on roofs
Here is some interesting info.

Very interesting but the mug shots at the end look like they should be hanging in the post office on the "Most Wanted" list. [rofl]

Moved to Ford Focus and General Car Chat. Technical Chat is for technical discussions relating to general maintenance, electrical issues, engine trouble, and recalls.

Thanks for posting!

Vortex Generators have been used on airplanes for decades now, its amazing what a little "fin" can do. At least on an airplane they increase fuel efficiency, create more lift, less drag, lower stall speeds, reduce takeoff distance, increase rate of climb, increase max takeoff weight. and the ones on the plane I fly the help reduce the accumulation of ice over the wing.

Lately Ive been seeing people add these to their cars and trucks, and while the idea is there, there has to be a bit of engineering on the proper placement of the generators so i wonder if they help or hurt aerodynamics when they are placed in random places.

To me they are right up there with clear tail lamps and big muffler tips....On my car?...Oh Hell NO! I would doubt many streetcars go fast enough to have much, if any effect. They say the shaker on my mach 1 doesn't have much effect until 90+ mph. (And of course I would never even consider going near that fast...LOL)

Do they produce AC or DC?

Maybe I need to read all the way through it first but... I didn't think they created electricity.

It's just an old airline Boeing training course joke!

So my Sedan needs a giant wing and little triangles of the roof if I want to go fast?
and here I thought I was cool for not having a rear wing, I guess Im only fooling myself!

Good info though, thanks

They're Japanese, you don't smile for the company photo. Serious occasion.
